Today, Gate Commutated Thyristors (GCTs) are used in high power converters due to their high current switching and high voltage blocking capabilities. The optimization of these power switches is of utmost importance in order to increase the efficiency of the complete system. To achieve that, a novel semiconductor device was introduced, the Dual-GCT [1][2]. In this paper, a Gate Drive Unit (GDU) for...
The performance of high-power inverters strongly depends on the characteristics of the underlying semiconductor device. The design of such devices is typically a compromise between on-state losses and switching losses. The idea analyzed in this paper is to combine two GCT devices into one single wafer, one switching-optimized GCT structure and one conducting-optimized GCT. By a parallel connection...
In the past, overhead lines, cables, transformers and circuit breakers represented the core components of electric power systems. However, in light of a considerable and still increasing share of renewable energy sources in grids, a change in electricity infrastructure can be observed. Over the last decades advances in power semiconductor devices have paved the way for innovative equipment such as...
Total artificial hearts (TAHs), available in today's market, have the disadvantage of wear-prone components. Thus, their expectation of life is limited and the devices can only be used for temporary and not destination therapy. Durability- and wear-free operations are the critical requirements, as failure is an immediate threat to the patient's life. These attributes are combined in linear motors...
